What can be a consequence of grossly overfeeding fluoride?

The consequence of grossly overfeeding fluoride can lead to illness and bad public relations. Excessive fluoride can cause fluorosis, which affects dental health and may lead to negative health impacts such as nausea or abdominal discomfort. When communities or water supply managers fail to regulate fluoride levels properly, it can result in widespread public concern, leading to distrust and negative perception towards those responsible for public health and water safety. This can create challenges in maintaining community relationships and addressing any potential health consequences.

The other consequences mentioned in the options relate to different aspects of fluoride exposure or environmental conditions but do not encapsulate the broader implications of overfeeding fluoride, particularly regarding community health and perception. For instance, while children developing permanent teeth is an important aspect of health, the primary immediate effects of overfeeding fluoride are more closely linked to general health issues and public opinion.
